The aim of the present study was to evaluate the efficacy of dose modification based on the risk factor for linezolid-induced thrombocytopenia. A multivariate logistic regression analysis performed in the observational study showed that low body weight of <55 kg (odds ratio [OR]: 33.2, 95% confidence interval [CI]: 2.16–510.1, P = 0.012) and the baseline platelet count of <200 × 103/mm3 (OR: 24.9, 95% CI: 1.53–404.7, P = 0.024) were found to be risk factors for linezolid-induced thrombocytopenia. In the subsequent intervention study, in which daily dose of linezolid was set to 20 mg/kg in patients with either one of the risk factors or 1200 mg in those without any risk factor, the onset of thrombocytopenia was significantly prolonged in the intervention study group (P = 0.043), without reducing clinical efficacy. These findings suggest that dose adjustment of linezolid is effective in preventing thrombocytopenia without reducing its clinical efficacy in patients having risk factors. 相似文献

Phase III randomized, clinical trials are primarily designed to evaluate overall treatment-outcome comparisons. Although valuable data are gained from such comparisons, it is difficult to draw meaningful inferences about potential outcomes differences in specific patient groups and infection types. It is well established that clinical outcomes are dependent on host, treatment- and pathogen-related factors and understanding which groups benefit from one treatment relative to another is of great importance. This study sought to determine if clinical success in the treatment of complicated skin and skin structure infections (cSSSI) caused by methicillin resistant Staphylocccus aureus (MRSA) with linezolid or vancomycin varied across subpopulations and infection type. Data from 3 prospective, randomized trials evaluating linezolid and vancomycin for the treatment of MRSA cSSSI were pooled. Treatment related differences in outcomes were found, on both the absolute and relative scales, for most subpopulations and infection types. Identifying treatment differences in outcome by patient subpopulation can enhance clinical decision making. 相似文献

Linezolid is an oxazolidinone antibiotic. Linezolid-associated lactic acidosis has been reported in 6.8% of linezolid-treated patients. Lactic acidosis is associated with poor clinical outcomes, with high blood lactate levels resulting in organ dysfunction and mortality. This case report describes the development of lactic acidosis in a 64-year-old Chinese woman who had received 33 days of treatment with antituberculosis drugs and 28 days of treatment with oral linezolid for tuberculous meningitis. Severe lactic acidosis was reversed by withdrawing antituberculosis drugs and using continuous venovenous hemodiafiltration (CVVH). When the patient's condition was stable, she was transferred to the infectious disease department, and antituberculosis drugs, with the exception of linezolid, were reintroduced. This did not result in recurrence of lactic acidosis. The causal relationship between lactic acidosis and linezolid was categorized as ‘probable’ on the Adverse Drug Reaction Probability Scale. This case demonstrates that CVVH has potential as an alternative to discontinuation of linezolid alone for rapid reversal of linezolid-associated severe lactic acidosis. 相似文献

In this study, in vitro synergism in combinations of agents as ceftriaxone/dalbavancin, ceftriaxone/linezolid and ceftriaxone/daptomycin against MRSA strains were investigated. Thirty clinical MRSA strains were tested. The minimum inhibitory concentrations of all antibiotics were determined using reference broth microdilution method. In-vitro activities of antibiotics combined against the strains were tested using two-dimensional checkerboard microdilution method. Results were interpreted as follows: synergy = FICI ≤0.5; ‘no interaction’ effect = FICI ?0.5-≤4; antagonism = FICI ?4. The MIC50, MIC90 and MICrange of ceftriaxone, daptomycin, dalbavancin and linezolid were found as 128, 1024 and 16-2048 mg/L; 1, 1 and 0.5–1 mg/L; 0.12, 0.12 and 0.03–0.12 mg/L; and 1, 2 and 1–2 mg/L, respectively. Our results showed that the frequency of synergistic effects (FICI: ≤0.5) of three combinations were all at the same rate of 77% (23/30). No in vitro antagonism (FICI >4) was observed. 相似文献

In infections following orthopaedic surgery, isolated staphylococci are reported to be methicillin resistant (MRSA) in up to 50% of cases. Linezolid, the first in a new class of antibiotics, has excellent efficacy against gram positive organisms that are resistant to other therapies and is 100% orally bioavailable. We report early results of its use for the treatment of resistant infections in orthopaedic practice. Infections were characterised according to the UK Nosocomial Infections National Surveillance Service classification of surgical infections as superficial, deep or organ/space. Osteomyelitis, joint sepsis and deep infection involving orthopaedic implants were included into the final category. Outcome was recorded as clinical, microbiological and blood parameter cure or fail. Over the 12-month study period, 54 patients received linezolid therapy, 41% of these had significant co-morbidity that might affect their ability to fight infection. Sixty-seven percent of infections were in association with implanted metal work. The majority of patients were treated with vancomycin for a short period before linezolid was used as oral 'switch' therapy for longer-term administration, allowing early discharge in all cases. MRSA was isolated in 87% of the patients treated. The mean length of linezolid therapy was 39 days (2-151). Clinical success was achieved in 90% of patients overall. Though there were no life-threatening complications, adverse event rates were significantly higher than those recorded in the literature, with 19% of patients needing to cease therapy. Linezolid offers an alternative to traditional treatments for resistant infections and can facilitate early discharge. Patients need to be monitored closely, particularly where long-term therapy is planned. 相似文献

The antibacterial activities of clindamycin, synercid, telithromycin, linezolid and mupirocin were evaluated against erythromycin-resistant Gram-positive coccal clinical isolates collected in Korean hospitals. In Staphylococcus aureus, synercid, linezolid and mupirocin were the most active agents. Against coagulase-negative staphylococci (CNS), synercid, linezolid and mupirocin were also active. Telithromycin and synercid resistance was common against enterococci, only linezolid and mupirocin were active. The reason of low activity of telithromycin against staphylococci and enterococci is because most of the isolates were constitutively resistant to erythromycin. Synercid, telithromycin, linezolid and mupirocin were active against streptococci. 相似文献

利奈唑胺、万古霉素对甲氧西林耐药的金黄色葡萄球菌的防耐药突变体选择浓度的研究 总被引:1,自引:0,他引:1
目的:比较利奈唑胺、万古霉素对耐甲氧西林金黄色葡萄球菌的防耐药突变选择能力;研究防耐药突变体选择浓度(MPC)和最低抑菌浓度(MIC)的相关性。方法:采用琼脂微量稀释法测定利奈唑胺、万古霉素对35株耐甲氧西林金黄色葡萄球菌(MRSA)临床分离菌株的MPC和MIC;采用线性回归法比较利奈唑胺、万古霉素对MRSA的MPC和MIC的相关性;结合人体药代动力学数据,预测利夺唑胺、万古霉素对MRSA的防耐药突变体选择能力。结果:利奈唑胺、万古霉素对35株MRSA的MPC90值(抑制90%的细菌发生细菌耐药的最低防耐药突变体选择浓度)分别为16.8μg/mL,选择指数(MPC90/MIC90)均为8。两药对MRSA的MPC和MIC的线性相关系数R^2分别为0.32和0.008。结合两药药代动力学参数,利奈唑胺药物浓度在整个给药间隔落在耐药突变选择窗理论(MSW)中,万古霉素药物浓度在大部分给药间隔落在MPC之上。结论:万古霉素对MRSA的防耐药选择能力强于利奈唑胺;MPC和MIC的相关性差。 相似文献
